Specification of Letters Patent.

Patented Mar. 14;, 1911.

Application filed September 9, 1910. Serial No. 581,204.

To all whom it may concern:

Be it known that I, CHARLES SEIDMAN, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful lVoven Tubular Muffler, of which thefollowing is a specification.

My invention consists of a novel woven tubular muffler which isreinforced in a novel manner at the edges at which occurs the greatestwear on the fabric.

It further consists of a novel construction of a woven tubular mufflerin which opposite edges of the same are woven in a novel man nerrelatively to the body portion of the muffler.

It further consists of other novel features of construction, all as willbe hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in theaccompanying drawings those embodiments thereof which are at presentpreferred by me, since the same have been found in practice to givesatisfactory and reliable results, although it is to be understood thatthe various instrumentalities of which my invention consists can bevariously arranged and organized and that my invention is not limited tothe precise arrangement and organization of these instrumentalities asherein shown and described.

Figure 1 represents a plan view of a woven tubular muffler embodying myinvention and showing a portion of the pattern. Fig. 2 represents a planview of another embodiment of my invention. Fig. 3 represents a planview, on an enlarged scale, of a portion of my device showing therelatively closer weave. Fig. 1 represents a plan view, on an enlargedscale, of a portion of my device, showing a stripe which may be employedif desired. Fig. 5 represents a diagrammatical view showing more clearlythe manner in which the muffler is woven.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings, 1 designates a muffler embodying my inventionwhich may be shaped intermediately of its ends, as seen at 2 in Fig. 1,in order to more closely fit the neck of the wearer and the ends, ifdesired, may form a fringe 3, although in many cases arising inpractice, I form the mulller of uniform diameter and dispense with thefringe at the ends, as indicated in Fig. 2.

In mufflers, as heretofore constructed,in so far as I am aware, it hasbeen deemed impossible to reinforce the mufller at points of greatestwear without varying the appearance of the mulller. In my presentinvention I accomplish this by passing the wefts around each warp, aswill be clearly understood by reference to Fig. 5. In the body portion 4of the mulller the weft 5 passes around two of the i'arp threads (3while at opposite edges of the muiller, as indicated at 7 the weft 5passes around a single warp (3, so that at the points of greatest wearthe fabric will be reinforced but, owing to the manner in which the sameis woven, the body of the fabric and the edges will have the samegeneral appearance. In the present instance, I reinforce the edges ofthe fabric by passing the weft 5 around twelve of the warp threads (5but it will of course be apparent that the number of single warp threadswhich are reinforced may be varied in accordance with the an'iount ofmaterial which it is desired to reinforce.

In somecases it is desirable to weave a stripe in the mulller, asindicated at 8, although the cha 'acter of such stripe may be varied asdesired and in many cases the same may be entirely dispensed with.

It will be apparent that a mulllcr constructed in this manner will beseamless and will not be liable to be ripped or torn.

It will be apparent that if desired a separate lining may be employed incoimection with the mulller in order to give it additional weight orbody.

Owing to the manner in which the mulller is reinforced at the points ofgreatest wear the durability and life of the muiller is greatlyincreased.

It will be evident that since the entire muiller is formed during theweaving operation the cost of production is greatly cheapencd relativelyto the cost of mzmufacturing mulllers in the ordinary way.

Owing to the novel manner in which the muffler is reinforced atdiametrically opposite points the same retains its shape under allconditions and is not liable to become distorted when the same isstretched or pulled.

In some cases it is desirable to form a cross bar or stripe 9 during theoperation of weaving and any number of these stripes may be employed sothat in proximity to the ends of the muiller the body portion thereof isrelatively thicker and stronger.

It will now be apparent that I have -de-- features of advantageenumerated as Cl6Sll'- able in the statement of the invention and theabove description and while I have, in the present instance, shown anddescribed a preferred embodiment thereof which has been found inpractice to give satisfactory and reliable results, it is to beunderstood that the same is susceptible of modification in variousparticulars without departing from the spirit or scope of theinventionor sacrificing any ofits advantages.

Having thus described my invention, what I claim as new and desireto-secure by Letters Patent, is

1. As a new article of manufacture, a Woven tubular inutller having itsbodypor- 20 tion composed of wefts passing around a plurality of-Warpthreads and having a longitudinally extending reinforcement of the samematerial as said muffler in the body portion thereof, said reinforcementconsist-,

ing of a closer weave at diametrically opposite portions of the m'ufilerformed by the wefts passing around each warp.

2. As a new article of manufacture, a woven tubular mufiler, having itsbody portion composed of wefts passing around a plurality of Warpthreads, while at itsopposite edges the Weft passes around each warp H.S. FAIRBANKS, I C. D. MGVAY.
